In 1908, something exploded above the remote Siberian forest of Tunguska with enough force to flatten roughly 2,000 square kilometres of trees — and more than a century later, no impact crater has ever been found, because the object, probably a small asteroid, appears to have blown itself apart in the atmosphere.

The 1908 Tunguska event flattened ~2,000 sq km of Siberian forest and left no crater. The reason is an airburst: a stony asteroid that disintegrated several kilometres up. What the evidence shows, what is still argued, a…

From birds to fish, how extreme heat causes wildlife to suffer

Like humans, wildlife is increasingly vulnerable as climate change fuels longer and more intense heat waves, disrupting feeding and breeding and, in extreme cases, proving fatal.

Over ten workdays, researchers sent employees on 15-minute lunchtime walks through a park, and afternoons changed — sharper concentration, less fatigue, with much of the lift carried by how genuinely people enjoyed the walk.

Over ten workdays, researchers sent employees on 15-minute lunchtime walks through a park, and afternoons changed — sharper concentration, less fatigue, with much of the lift carried by how genuinely people enjoyed the walk.

Most lunch breaks are not really breaks. A sandwich at the desk, the screen never quite off, an eye on the next message. The afternoon arrives already flat, and you spend it pushing a boulder that did not feel this heavy…
